But this invokes the delegate again...
I have set up a flag to know if it is the second time the delegate
is invoked
(first time: user select quit,
second time: the user don't want to save and the [NSApp
terminate:self] is called)
But is seem quite tricky while everything else in Cococa is much
more straightforward.
I feel I'm missing something about the single window application
architecture...
Anyway,
thank you!
Look at the delegate's appShouldTerminate - it can handle either
terminating immediately (or not), such as in the case where the
"data" is already saved, or it can return a value meaning "I need to
ask the user something - I'll get back to you". With that case, you
can present your sheet, and when they're done you can tell NSApp
"yes, now you can finish quitting like you started before".
It basically handles exactly what you want...
